Original application filed 'october '3, 1910, Serial No. 585,116.Divided and this application filed May 23.

' 1912. Serial No. 699,137.

Beverly, in the county of Essex and State of Massachusetts, haveinvented certain new and useful Improvements in Sewing- Machines; and Idohereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make-and use the same.

The present invention relates to shoe sewing machines employing a curvedhook needle, and more particularly to a needleoiling device for suchmachines.

It has heretofore been proposed to provide a curved hook needle sewingmachine with a device for applying oil to the needle so as to preventthe needle, from sticking in the needle guide or in the work.

i The rimary object of the invention is to provide an improved needleoiling or lubricating device which is simple in con.- struction,eflicient in operation, and is not liable to injury during'the operationof the machine.

With the above object in view one feature of the invention contemplatesthe provision in a shoe sewing machine having a curved hook needle of aneedle oiling device arranged to contact with the needle and to be movedaway from the needle by the needle carrier during the advancing movementof the needle carrier. By arranging the oiling device so that it ismoved away from the needle by the needle carrier during the ad vancingmovement of the carrier, the oiling device is enabled to contact withand apply oil to the needle-in a satisfactory manner, and is moved outof the way of the forward portion of the carrier as the carrieradvances.

' F i'rther features of the invention consist of certain constructions,arrangements and combinations of parts hereinafter described andclaimed, the advantages of which will is a curved barbed needle of theusual con- I struction and is secured by a clamping block to anoscillatory needle carrier?) journaled in any suitable manner in themachine. The movements imparted to the needle carrier and the mechanismfor operating the same in the machine illustrated in the drawing are thesame as shown and described in applicants co-pending application SerialNo. 585,116, filed October 3, 1910, of which the present applicationis'a division.

The oiling device for the needle consists of an arm 4 pivotally mountedat 5 on the guide 7 for the needle carrier and provided at its forwardend with an opening to receive the mass of absorbent material 6. Therear end of the arm 4 is connected by a coiled spring 2 with a lug onthe guide 7, the tendency of which spring is to IIIOYQ the arm 4 so asto bring the mass of absorbent material 6 into contact with the needle.The mass of absorbent material forms an oiling pad to which oil issupplied by means of a tube 8 leading from an oil cup 9 to a positiondirectly over the forward end of the arm 4. To prevent the needlecarrier during its forward movement from coming in contact with theforward end of the arm 4:, the arm is so shaped and arranged that aportion of the arm substantially'midway of a its length extends into thepath of movement of the .needle carrier. The arm is thus engaged by theneedle carrier during its forward movement, and the forward end of thearm and the oilin'g padare raised out.

of the path of movement of the' leading edge of the needle carrier.

Having explained the natureand object of the invention, and havingdescribed a mechanism embodying the same in its preferred form, what isclaimed is 1. A sewing machine, having, in combination, stitch formingdevices including a curved hook needle, a needle carrier, and a movablysupported needle oiling device arranged to contact with the needle andmeans actuated by the needle carrier for moving the oiling device awayfrom the needle dur ing the advancing movement of the carrier.

2. A sewing machine, having, in combination, stitchforming devicesincluding a curved hook needle, a needle carner, and a pivotally mountedarm provided with an oiling .pad [arranged to contact with the needle,said arm extending into the path of the needle carrier so as to beactuated thereby during the advancing movement of the needle carrierto'raise the pad from-the 3. A-sewing machine, having, in combination,stitch forming devices including a sothat it 1s engaged by the needlecarrier and moved away from the needle by the needle carrier during theadvancing movement of the needle carrier.

' 4. 'A sewing machine, having, incombination, stitch forming devicesincluding a curved hook needle, a needle earner, an 011- ing padarranged to remain stationary in:

contact with the needle during a portion of the needle movement in eachdirection,

means for raising the pad from the needle during the latter portion ofthe advancing movement of the needle.

5. A sewing machine, having, in combina tion, stitch forming devicesincluding a curved hook needle, needle actuatingmechanisin, an oilingpad arrangedto' contact with the needle, a carrier therefor mountedindependently of the needle actuatingmechanism, and means-for raisingthe pad from the needle during the latter portion of the advancingmovement of the needle.
